摘要
该文以丹河新桥为例,通过计算铰点极限弯矩的方法确定圬工拱桥极限承载力,综合考虑了拱的受力状况以及材料特性,为圬工拱桥极限承载力的研究提供了一个新的方向,亦可供钢筋混凝土拱桥极限承载力的确定做参考。
Taking Danhe Bridge as an example,this paper determines the ultimate bearing capacity of masonry arch bridge by calculating ultimate bending moment of hinge point,and considers the loading state of arch bridge and material characteristics comprehensively.It offers the new direction for researching the ultimate bearing capacity of masonry arch bridge,and the reference able for determining the ultimate bearing capacity of reinforced concrete arch bridge.
